562 = 24.97% I calculated it, and for 25% you need 562.5 points, is that half a point really needed? if so then I'm one point short there.

Wich brings me at a grand total of 2172 points, some points still left until 2250. The idea is to have the Saurus take some of the beating while the Stegadons dish out the damage, the Slann of course being the powerful caster reigning destruction upon his enemies and the skirmishers picking out stragglers and being a nuisance. And the Cold ones being the hammers. That's what I got so far. Any feedback will be very helpful seeing I don't have much experience with Lizardmen yet.

You most definitely need the minimum core choice allotment. Try to get the Warrior units up to 20 apiece by dropping all but the musician on the Calvary unit since it's just going to be a harassing unit anyways. Although I've never attempted giving the BS to the Chief, it sounds like a terrible idea when you could give it to the Slann instead. You will probably want either Chameleons or Terradons (or both) for war machine hunting and having salamanders is never a bad choice either. Food for thought.

Your slann can't have two arcane items. Give the scroll to the priest.

Split the salamanders up into three units, and give each an extra handler.

I don't think the one stegadon will accomplish much, and will just be a huge target for any warmachines.

I would lose a few chameleons and bump up your warrior units. Maybe add some to one unit to get it up to around 30. Drop the other down to around 18 for a flanking unit, or up to at least 24 for a main line unit.

Banners for the temple guard and cold one riders can be useful as well.
